This is Common problem in HP server blades default configuration. The default setting locks ILO and you see that message till you reset ILO.
To fix the problem go to Problematic Blade >ILO >Web administration
Remote console>Settings and change Remote Console Acquire to Enabled



This saved me a lot of trouble.
thanks very much!

Your welcome.
Always happy to help
I’m running a DL360, not a blade, but my iLO kept saying that message all the time. I went into the network properties of the iLO web admin, swapped the DNS settings and hit Apply. That forced a reset of iLO and I was back in business. Thanks for pointing me in the right direction!
Thanks for the tip – as kbgeoff said, this is also a problem on the HP DL360/ML360 iLO units, so appreciate the help sorting it!
Excellent
Thanks
